Step 1: Assign variable for the unknown that we need to find.
Let 'x' be the licence fee for a car that cost $9,900.
Step 2: Set up a proportion based on the given information.
Step 3: Solve for x
To get x alone we need to undo whatever is done to x. So multiply 9900 on both sides of the equation.
Simplifying fraction on both sides of the equation, we get...
Conclusion:
<u>$88.24 is the licence fee for a car that cost $9,900.</u>
Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
Answer:
(x + 4)² + (y - 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 4, 9) and r = 10 ÷ 2 = 5, thus
(x - (- 4))² + (y - 9)² = 5², that is
(x + 4)² + (y - 9)² = 25
67.27
155 = 1.55 x 43.4 = 67.27
